.L anpertains to make and use the same.

ine present invention relates to an improved guard for inseam-sewing machines.

Shoes are frequently or usually lasted with a an upper somewhat larger than is necessary to reach over the edge of the sole or insole, so r the upper has been secured by the lasting-tacks or other means a margin of va rying and frequently considerable width prots upwardly from the edge of the sole. r. the shoe is narrow, and particularly at 1e shank portion of the shoe, the margin of 1c upper frequently projects so far from one i 7. s cause inconvenience in sewing the l u. at the opposite side of the shoe, since urplus upper material projects into the space in which the sewing instrumentalities he machine are moving, so as to be pierced the needle or the feed-point or to interfore with the proper looping of the needle by leper. The danger of such accidental contact necessitates either the prehnnnary i nnnng of the upper to reduce the width of margin or other precautions on the part of the sen ing-machine operator and causes :1 hiconvenience and loss of time.

ie object of the present invention is to r guard for use on inseam-sewing the curved hooked-needle t pe, ent accidental contact bescribed, as defined in the claims.

In the drawings, Figures 1 and 2 are front Levations of portions of an inseam-sewing une in which the invention is embodied Fig. 3 is a side elevation of the same s, showing also in section a shoe upon which the machine is operating.

imparted to these instrumentalities and invention is illustrated as embodied in an inseanrsewing machine of the well-known Goodyeartype, which is described with substantial accuracy in Letters Patent of the United States No. 412,704, granted October 8, 1889, to French and Meyer. In the drawings the curved hooked needle 1, the looper 2, the feed-point 3, and the channel-guide 4 are all constructedand operated as shown in the patent referred to. The feed-point 3 and the channel-guide 4 are mounted upon a slide 5, by which the lateral feeding movements are 6: which forms, therefore, part of the feed mechanism.

The guard forming particularly the subject of the present invention comprises a small outwardlydnclined plate 6, provided with a slotted shank 7, by which it is secured upon thechannel-guide carrier 8, the shank 7 and the channel-guide 4 being both secured to the carrier 8 by the same screws 9.

As the feed-point 3 falls and enters the, channel, the needle being retracted and the looper idle, the guard occupies the position of Fig. 1 directly in front of'the feed-point and holds the margin of the shoe-upper away from the feed-point, as shown in Fig. 3. In the subsequent left-hand feeding movement of the feed-point and channel? guide the guard being connected, as above described, with the feeding mechanism moves with the feed-point to the position of Fig. 2, in which it is directly in front of the needle. During the subsequent advance of the needle'and the looping operation of the looper the guard holds-the upper away from these parts.

The lateral movement of the guard resulting from its connection with the feed. mechanism,while not an essential feature of the invention in its broader aspects, is useful, as it permits the use of a very narrow guard 5 which does not substantially obstruct the View of the operator or interfere with the manipulation of the work. It also prevents any retardation of the feed movement which might result from friction between the guard to") and the sole or upper of the shoe in contact with it. The slotted shank of the guard permits vertical adjustment, and the manner in which it is secured to the machine permits its application without any alteration or additional parts whatever in the machine The present invention is not limited to the details of construction and operation of the illustrated embodiment, but may be embodied in other forms broadly defined in the claims.

Having now described the invention, What is claimed is 1; A11 inseam-sewing machine having, in combination, acurved, hooked needle, a looper, and a guard located in front of the needle and looper so as to prevent contact between these parts and the upper projecting from the side of the shoe opposite to that on 1 which the machine is operating, substantially as described.

2. An lnseain-sewing machine having, in

combination, a curved, hooked needle, a j looper, a feed-point, and a guard interposed Q between the feed-point and the upper pro- 1 jecting from the side of the shoe opposite to that on which the machine is operating, substantially as described.

3. An inseam-sewing machine having, in combination, a curved, hooked needle, a looper, feed mechanism including a feedpoint, and a guard located in front of the ieed point and connected With the feed in unison with the feed-point into position i; the needle and looper, substa t l scribed.
